Latest Patents
Hashimoto's latest patents include a method and apparatus for manufacturing interior permanent magnet-type inner rotors. The first patent describes a manufacturing method that prevents thermal demagnetization during the shrink fitting of a rotor core to a rotating shaft. This method involves a shrink fitting step where the rotor core is heated and fitted onto the shaft, followed by a filling step that utilizes a flowable mixture of binder resin and anisotropic magnet particles. This innovative approach allows for the concurrent production of inner rotors with both anisotropic bond magnets and conventional sintered magnets.
The second patent focuses on the apparatus used for this manufacturing process. It features a three-layer mold structure and incorporates the same shrink fitting and filling steps as the first patent. This apparatus enables the efficient production of both types of inner rotors in an existing IPM motor manufacturing line, showcasing Hashimoto's commitment to enhancing manufacturing capabilities.
